Definitions

• the invention relates to a method for influencing plant growth, for. B. of rice or ornamental plants by treating the seeds with a polycyclic nitrogen-containing organic compound. For plants that thrive in arid surroundings, it also has a beneficial influence on the water balance of the plants.
• the stability of cereal plants such. B. of rice depends u. a. on the length of the stalk. A reduction in the same reduces the corresponding lever torque and thus the risk of static breakage. The risk of stored grain stocks is reduced.
• a further object of the invention arises from the need to influence the growth of plants in such a way that they thrive better under conditions of lack of water, ie in arid surroundings, and / or consume less water.
• Saving water not only serves to conserve it in areas with a lack of water, but also counteracts the salinization of the soil surface through evaporation.
• phenyl radical which is substituted by halogen, fluoroalkyl having 1 to 2 carbon atoms, N0 2 or C 1 -C 3 alkyl
• the amount of treatment used being chosen in this way that there is an amount of active ingredient of less than 100 g of active ingredient per ha for the sown soil area.
• the improvement of the use of the water available to the plants can e.g. B. by reducing the transpiration but also by changing the root: shoot ratio.
• the reduction in perspiration is understood to mean the reduction in water excretion in gas form through the surface of the crop plants.
• Seeds of the rice variety "Tainung 67" were treated on November 29, 80 for 24 hours at a temperature of 30 ° C by dip dressing with a dispersion of the active ingredient in water. Seeding in seed boxes took place on December 12th, 80th. The height and rate of growth were determined 13 and 21 days after sowing. The following data were obtained:
• Seed of rice of the variety "Kaohshing 141" was treated on November 29, 80 for 24 hours at a temperature of 30 ° C by dip dressing. Seeding in seed boxes took place on December 5th, 80th. The emergence was on December 7th, 80th. 13 and 21 days after sowing, the height and Growth rate determined. The following data were:
• Seed of rice of the variety "Tainan 5" was treated on April 18, 1980 for 24 hours at a temperature of 30 ° C by dip dressing. Sowing in seed boxes took place on April 23rd, 80th. On April 25th, 80th the seeds came up. The height of growth was measured 13 and 21 days after sowing. The following data were obtained:
• Inabawase rice seed was treated on April 27th, 80 for 24 hours at a temperature of 30 ° C by dip dressing. The casserole was observed on 04/30/80. Seeding in seed boxes took place on April 28th, 80th, 7th, 9th, 13th, 19th and 28th day after sowing, the height and growth rate and 28 days after sowing the leaf and root weight per plant were determined. The following results were obtained:
• the initial inhibition of growth after seed dressing is followed by a significantly increased growth rate compared to untreated plants. This is related to a significantly expanded root: leaf weight ratio of 1.14-1.61: 1 compared to approximately 1: 1 in untreated rice plants.
• Such treated young plants are more robust and resistant at the time of transplantation into the field. After transplantation, they develop faster than rice plants from untreated seeds.
• the treated plants also show this development acceleration after the transplantation with regard to the number of tillers, the root length and the dry matter weights.
• Rice plants treated with substance A reach the time of transplantation in a compact and vigorous state. They survive the stress of the transplant in the field better and then develop faster.
• Inabawase rice seeds were treated on April 27, 78 for 24 hours at a temperature of 30 ° C by dip dressing. Seeding in seed boxes took place on April 28th, 78th. 78 the casserole was observed. 7, 9, 13, 19 and 28 days after sowing, the height and growth rate and on the 28th day after sowing the leaf and root weight per plant were determined. The following results were obtained:
• leaf weight ratio based on the dry matter, the plants treated with substances C, D and E hardly differ from untreated plants.
• the wilting symptoms were significantly reduced by the treatment and the water potential in the leaf was increased.
• Seed of maize 3369A was treated in the form of a wet dressing with active ingredient A, sown in the field and grown under water. 31 days after sowing, the wilting symptoms and the height of these plants were assessed.
• Example 2 Analogously to Example 1, the wilting symptoms of the treated plants were also significantly reduced compared to untreated plants. A significant improvement in water use can also be seen here. The treatments also resulted in an inhibition of length growth of between 10 and 20%.
• Seed of the maize variety 3369A was treated for 2 hours at a temperature of 25 ° C. by dip dressing with a dispersion of the active compound A in water. A batch of the same seed was treated equally with pure water.
• the yield parameters were evaluated when the grains ripened. In this example, too, the yield factors could be significantly improved.
• Aqueous application forms can be prepared from emulsion concentrates, pastes or wettable powders (wettable powders), oil dispersions by adding water.
• emulsions, pastes or oil dispersions the substances as such or dissolved in an oil or solvent can be homogenized in water by means of wetting agents, adhesives, dispersants or emulsifiers.
• concentrates consisting of an active substance, wetting agent, tackifier, dispersant or emulsifier and possibly solvent or oil, which are suitable for dilution with water.
• the formulations contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90% by weight.
• the combination or mixture with other growth-regulating active ingredients can prove to be advantageous, as u. a. with ethylene-forming substances of various chemical structures (e.g. phosphonic acid derivatives and silanes, ethyl hydrazines), onium compounds (e.g. trimethylammonium, hydryzonium and sulfonium salts, derivatives of morpholinium, piperidinium and pyridazinium compounds).

• the amount according to the invention can vary in the amount used.
• the amount used depends mainly on the type of effect desired.
• the application rate is generally between 0.01 and 99 g / ha, preferably between 0.01 and 30 g of active ingredient per hectare, a conversion taking place in the case of the seed designation, such that the amount used for dressing is that for the area to be sown amount needed.
